On what happened in Cambridgeshire and the DLR, that will be the subject of an internal inquiry by Cambridgeshire Constabulary. It will reflect on that, and I suspect it will produce a report that surfaces the issues. We use facial recognition in a number of ways. There is the opportunity, potentially, to look at a crowd and determine from a database of known individuals—or even, for example, missing people —whether they are in that crowd by identifying them. That is one way. Police can use operator-initiated facial recognition, which is an app that allows officers to take a picture of a person and compare it against any database we have of people who have been convicted of offences, and others. There are ways in which we can have live footage of people passing a camera, which we have been testing and monitoring. British Transport Police, under my noble friend, will be piloting live facial recognition technology very shortly. That pilot will look for a short period—six months —to determine whether it is valuable and what lessons can be learned. However, as the right reverend Prelate said, it needs to be put into a legal context, and we will also look at that, potentially later this year. The issues about what happened, we need to examine. I do not know as yet what lessons are to be learned from the CCTV and how it was used, but that is what the investigation will lead to. I want to go back to one point the right reverend Prelate mentioned, which is the early announcement of what happened and who, potentially, is the subject of the investigation. That is an important point, because we have learned from previous examples that putting information into the public domain—although not, in the first instance, the name of the individual, until any charge is made—takes away social media and other speculation that can lead to people having false information that leads them down alleyways that are not productive of public good and public order. I welcome the fact that in this instance, early information was given, and I would expect that in any situation. This individual was described in one way, others may be described in other ways; but the fact that further information was given about who the individual of interest is, is extremely important.
